Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595582, here are decompositions:

13 + 31595569 = 31595582
199 + 31595383 = 31595582
211 + 31595371 = 31595582
331 + 31595251 = 31595582
373 + 31595209 = 31595582
409 + 31595173 = 31595582
523 + 31595059 = 31595582
619 + 31594963 = 31595582

Showing the first eight; more decompositions exist.
